Bacterial Pathogenicity-
A pathogen is a microorganism that causes disease to animal, plants or insect. Pathogenicity is the ability producing disease in the living organism of human body. Virulence is the degree of pathogenicity of the microbe which express the pathogenicity to a human body and produce the disease. The virulence of pathogen can be determined as they are biomechanical, genetic or structural feature (Todar, K 2012). People gets attack and fall in sick if the degree of susceptibility or resistance of human body is lesser than the ability of the virulence of pathogen. Pathogenic bacteria can be invasiveness that can invade the living tissue, toxigenesis that can produce toxin in the living organs of human body.
